All of the above Jase, I have 4 soda stream bottles that I rotate and it does tend to be a ******* when changing/moving kegs. becuase they are little fookers they will fall over easily when they have a top heavy reg on top, this is not really a problem as I manage it but they take up space. I am not concerned about the Reg being in the fridge appa from the fact I can't see it. My upcoming set up is a chesty with only kegs and yeasty inside. I like the idea that I can see where the kegs are at (gas wise) from the outside. If its not an issue for YOU reg and bottle will be fine inside.
Cheers Brad
